There are many options to consider when purchasing a projection system. The right projector for you will depend on the operating environment. This guide will begin by explaining some of the more common terms used when discussing projectors.
Projector lamps are one of the few parts of the projector you will need to maintain. They periodically need to be replaced. Lamps generally last around 2000 hours and cost around $200-400 (sometimes more). Some projectors have low power modes that will extend the lamp life to 3000 or 4000 hours. This is an important consideration for the overall cost of ownership. Also be aware of how many lamps your projector uses. High brightness models will sometimes use a dual lamp system. It’s important to understand that lamps are not covered under the general warranty of the projector. They’re typically only covered for 90 days or sometimes up to one year depending on the manufacturer.
LED and Laser/LED hybrid light source projectors do not have replaceable lamps, however, the light source is typically good for up to 20,000 hours of use.
All projectors have to be mounted at a specific distance from the screen in order to produce a certain size. It’s important to know how far you must mount the projector from the screen to achieve your desired size, especially if your mounting options are limited. You can determine the throw distance by looking at the throw ratio of the projector. Throw ratio is the relationship between your projectors distance from your screen and the width of the image. Almost all projectors have a zoom feature to adjust the size of the image so the throw ratio will be shown as a range, e.g. 1.1-2:1. For this example, in order to calculate the screen size width you will get from a specific distance, you would divide that distance by 1.1 to find the largest image size you can achieve and then divide by 2 to find the smallest image. To calculate the throw distance you need to achieve a specific size, you would multiple the size by 1.1 to find the shortest distance and then multiple by 2 to find the longest distance.
Projection calculators are also available to help you determine screen sizes. If you find that there are no projectors available that will work with your setup, there are specialty lenses available for “short” throw and “long” throw applications.
Projection Screens - Projection screens can be manual pull down, electric, portable, or fixed wall screens. The projection screen can sometimes cost as much or more than the projector itself so it’s important to factor this in to your budget.
Projector Mounts - Mounting hardware is available for virtually any projector on the market. Universal kits are available to make it easy for you.
Cables - Always be sure to check the outputs of the devices you plan to hook up to your projector and the inputs of the projector to make sure they are compatible. This is especially important in ceiling mount applications.
Fixed Brightness is very important in fixed conference room applications. Typically you are working in high ambient light conditions with a 100" diagonal image or larger. Having a bright projector will allow you to leave the lights on so your audience can take notes and brainstorm while still viewing the presentation.
Resolution - Typically, XGA resolution is adequate for conference room applications. However, if you’re going to be displaying highly detailed spreadsheets or CAD drawings, you should consider a higher resolution projector such as SXGA+. Additionally, most manufacturers have come out with bright, wide format projectors that display 16:10 images compatible with newer laptops and presentation software.
Other Considerations Many projectors have added features that can make your presenting life easier and more successful.
Wireless projectors for easy set-up. New wireless products are easy to setup and operate.
Networkability for control from remote location and added security
HDMI and Component video inputs for better quality video
Digital keystone correction for versatility in projector placement
Wireless mouse control, for freedom to move while you present
Lens shift for more convenient set-up
